Section 480-3-4-.08 - Haulage And Hoisting

(1) All hoisting equipment used on slopes and inclines shall be of ample capacity and of a design commercially recognized as safe.

(2) Hoists

(a) The drums or cable reels of hoist shall be provided with flanges that extend not less than two (2) inches radially beyond the outer layer of rope when the rope is fully wound on the drum or reel.

(b) All hoists shall have sufficient power to hoist the loaded unbalanced skip, car, trips of cars or vertically suspended load and shall be equipped with brakes adequate to stop and hold the fully loaded skip, car, trip of cars or vertically suspended load at any point on the slope, incline or hoisting range.

(3) Indicators

(a) All hoists shall be provided with indicators that plainly show the engineer or hoistman the position of the skip, car or cars on the incline or slope at all times, unless such engineer has full view of the load throughout the length of the slope or incline.

(4) Safety Devices

(a) All electric hoists shall be equipped with mechanical or electrical protective devices which will bring the hoists to rest within reasonable distance upon failure of power.

(b) Hoisting cable shall be firmly clamped to the drum or reel and at least three turns of the cable shall always remain on the drum or reel.

(5) Signals

(a) At every hoisting operation, an efficient signal system shall be provided, so that hoisting signals may be communicated from the foot of any slope or incline to the hoisting engineer. Calling or hand signals shall be accepted in lieu of such signal system if the engineer has full view of the car or skip throughout the length of slope of incline. Unless the engineer has such full view, no hoisting engine shall be operated when such signal system is out of order.

(b) Every signal system operated in connection with a hoisting engine shall be so designed and located as to provide either audible or visible signals to the hoisting engineer.

(6) Signal Code

(7) Riding

(a) Employees shall not be permitted to ride on conveyor or elevator belts.

(8) Record

(a) The owner, operator or superintendent of each quarry or pit shall provide and maintain a hoisting equipment inspection book and all hoisting equipment consisting of cars, skips, or other conveyances, cables, pulleys, sheaves, anchor shafts, safety switches, derails or any other such equipment shall be thoroughly inspected at least once each week and the results therefrom noted in this book at least once each month.

(b) The hoisting equipment book shall always be kept available for inspection by a duly authorized representative of the Department.

(9) Housing

(a) The hoisting equipment shall be housed in a suitable shed or building which will protect the operator and the equipment against the weather.

(10) Alarm

(a) A special alarm signal, which will produce a sound that can be plainly heard in all parts of the pit or quarry, shall be installed near the hoist engineer and shall be sounded when a car breaks loose on the incline, and shall not be sounded at any other time except for testing.

(11) Sheaves and Drums

(a) Sheaves and drums shall be at least as large as the minimum size recommended by the rope manufacturer.
